Abstract: ABSTRACT       Polymers  containing   tertiary   amine   groups,   and substantially free from active hydrogen atoms, are useful catalysts for the production of reaction injection moulded (RIM)  polyurethanes.   These  catalysts  do  not  interfere with the curing of paints on a moulded article or interfere in the urethane network. They are advantageously employed as a solution or dispersion in one of the polyurethane-forming components.     Advantageous catalysts are polymers made from monomers of the formula   wherein Y      = -0- or -NH-, R1     = H or CH3, R2-R7  independently = H, CH3, or alkyl, m      = 0-1, n    = 0-6,  and R8 and R9 independently = CH3, or alkyl,  or together with the nitrogen atom to which they are attached form a N-containing heterocyclic group.

Abstract: ABSTRACT     A method and apparatus for the thermal cracking and fractionation of petroleum heavy gas oil and simultaneously heavy crude oil feedstock below atmospheric pressure.  The feedstock is fed to a fractionator after heat ex-change with distillate fractions withdrawn from the fractionator  A heavy gas oil fraction is withdrawn from the fractionator, fed to a heater and subsequently to the top of a thermal cracking reactor, whilst the reduced or heavy crude stock is fed to the mid-section of the reactor.  The cracked products are quenched with the feedstock and fed to the bottom flash zone of the fractionator. The process may also be applied to existing crude oil topping still with modi-fications and operated above atmospheric pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A universal trigonometric function generator which is selectively programmable by pin-strapping to generate any of the standard trigonometric functions (sine, cosine, tangent, cotangent, secant and cosecant).  The circuit includes two identical sine-function generating networks each of which produces an output signal proportional to the sine of a corresponding angle input.          These networks are so interrelated that the composite output signal is proportional to the angle input of one network and inversely proportional to the angle input of the other network, producing an output A   , where A is a controllable amplitude, .theta.1 - .theta.2 is the angle input to one network, and ?1 - ?2 is the angle input to the other network.  By selectively con-necting the input terminals for .theta.1, .theta.2, ?1, ?2 to an angle control signal and reference voltages corresponding to 0° and 90°, any one of the standard trigonometric functions can be generated.

Abstract: 12.                     ABSTRACT OF THE DISCLOSURE         The present disclosure is directed to a portable cutter particularly useful in trimming and shaping standing growing trees of the evergreen type which has a cutting head mounted on one end of a rod, and a pistol grip type control handle on the other end.  A second handle is secured on the rod substantially midway between the control handle and cutting head.  A back pack having partial waist encircling support means with a belt and a securing buckle is provided with a pair of spaced apart vertical standards secured to said encircling support having a transverse connector there-between above said waist support.  The back pack is retained on the operator by a pair of shoulder strap connector means attached to each end of center of said transverse connector and connectable to said waist support.  Back pack extension and guide means is carried by and secured to at least one of the vertical standards.  A cutter suspension shock cord is adapted to be connected between the back pack extension and the cutter rod proximate the cutting head and being adjustable along the rod to permit adjustability for varying the apparent weight of the cutter from an apparent zero to an amount desired by the operator to provide maximum maneuver-ability with a minimum of operator fatigue.  The prime mover is carried by the back pack above the waist encircling support and supplies power to a motor connected to drive the cutting head and being carried thereby.  There is a selectively operable control connected between the prime mover and motor for selectively driving the motor under control of the pistol grip control handle.

The first jaw has a recessed, dished, clip-receiving channel in the innerface thereof extending from adjacent the tip of the jaw towards the hinge portion and effective to allow the first leg member of the clip to partially rotate in the channel, the channel having a length substantially equal to the length of the clip to be applied by the instrument.   The second jaw has a corresponding recessed, clip-receiving channel in the innerface thereof with integral clip-retaining means for restraining the second leg member of the clip against forward movement while permitting the rotation of the first leg member as the clip is closed by the instrument.

Abstract: Transitional Command Position Modification For A Controller Abstract of the Disclosure A controller for a manipulator or robot having a plurality of power-driven, signal-controlled links interconnected to permit relative motion therebetween to define plural degrees of freedom.  The links of the manipulator are control-led to perform movements, usually for working upon a workpiece, corresponding to stored sequences of command positions.  The controller stores, for each link, a sequence of command positions and is operable to add a further command position or a further sequence of command positions to the original sequence of command positions. In a non-synchronous mode of operation (where the movements of the robot are not synchronized with movement of the workpiece) or in a synchronous mode, a further command position is added to the end of the original sequence by producing a number of additional command positions and storing the additional command positions after the original sequence.  The last of the additional command positions is substantially equal to the further command position.  The position change per command of the additional commands is maintained generally constant.  In like manner, in the non-synchronous mode, the initial position of a further sequence of command positions can be added to the end of an original sequence.  In a synchronous mode of operation, such as with the manipulator command positions being processed at a rate to move the manipulator in synchronization with a conveyor, a first and a second sequence of command positions can be connected.  To do this, a portion of each original command sequence is replaced by a substitute sequence of command positions, preserving the correlation between the command position processing rate and the conveyor rate.

At a predetermined time during the on period of the lighting fixture, the lamp of the fixture is shut-off This shut-off time had previously been determined as one during which traffic in the area is at a minimum. A set time after the shut off, the lamp is lit once again, this time being selected as a time when traffic is re-appearing. When the ambient light reaches the shut-off level of the photoelectric cell, the lamp is shut off for the day.

Granted: 1989-04-25
Abstract: Abstract of Disclosure The present invention is directed to an improvement in an alignment system for a scanning mask aligner employing a pattern on the mask or the wafer or both in the scribe lines that run in the direction of scanning, the improvement comprising a viewing system having optical grids, a system for moving the patterns across the optical grids in the viewing system, the grids corresponding to the directions and spacings of the patterns so that light transmitted through the grid is strongly modulated, and circuitry for comparing the phase modulation from the mask and wafer alignment targets to obtain alignment error signals; further according to the invention, the same system used to measure alignment can also be used to measure how well the mask is focused on the wafer. In this case two images of the mask pattern are arranged so that one is slightly inside of focus and the other is slightly outside of focus, and by comparing the amount of modulation on the two channels it is possible to deduce which of the two is closer to focus and therefore how to shift the focus so that they are equal.
